' Application filed January 3,1899. Serial No. 700,900. (No model.)

ToaZZ whom it may concern.

Be'it known that I, PHINEAS F. KING, a citizen of the United States of America, and a resident of Cleveland, Cuyahoga county,0hio, have invented certain new and useful Improvements in Machines for. Making Fasteners, of which the following is a specification.

My invention relates to certain improvements in .a machine designed for-automatically producing fasteners of the character illustrated and described in an application filed by me June 1, 1898, Serial No'. 682,285. The object. of my invention is to produce a machine'which shall automatically and continuously act upon a strip or continuous length of metal to produce the completed fas tenor and to accomplish this result with one elevation of the machine with the dies and forming mechanism in section. Fig. 3 is an end elevation in the direction of the arrow A on Fig. 2.- Fig. at is a sectional view on the line a aof Fig. 2. Fig. 5 is a sectional View on the line I) Z) of Fig.8.

Fig. 17 is a perspective view of a strip of metal, showing the blank formed and looped, the eyelet completed, and. the Fig. 18'is an enlarged perjs'pective'view of the completed fastener. i

In the production heretofore-of shoe-hooks, fasteners, and likearticles it has been usual to feed the strip of metal to amachine which acts upon the same in the preliminary formation of -the blank. The blank so formed is then delivered to a machine which accomplishes the operation of bending and formation into the completed article.

I propose to subject the strip of metal to action for preliminarily forming the means by which the completed fastener is to be secured, to cut and bend the blank, to complete the fastener, and to expel or-discharge it from the machine by instrumentalities embodied in a single. machine and operating simultaneously and synchronously.

It will be understood that the primary ob jcct of my invention is toprovide means in one unitary machine by which to thus prepare or form one or more blanks for ultimate completion as fasteners by members or parts which act simultaneously and synchronously to accomplish this result. In my machineI provide dies with suitable propelling or actuating mechanism which are adapted to act upon a continuous strip of metal to form the eyelet or other means for securing the completed,fastener to an article or object, to cut out or form the blank, which consists of the base portion and an offset or stud constituting a part of the completed fastener, and also at the same time bend and form the completed fastener and expel it from the machine, these various steps in the process of preparation andformation being accomplished by one and the same movement of the parts simultaneously applied to and upon the con? tinuous strip. r My invention also has for its object the provision of means by which to effect a positive forward step-by-step fee'd'of the continuous stripfor certain predetermined and necessary equal distances in order that the dies and l forming mechanism may act upon the continuous strip at the proper points.

Referring now to the drawings, and particularly to ,Fig. 1, it will be observed that the.

machine is driven from a drive-wheel 20, operating a pinion 21, which is meshed with a gear-wheel 22, in turn meshing with the gear- Wheel 23.

The gear-wheels 22 and 23' are mounted, respectively, upon cam 'dri ve-shafts 24 and 25. As a detail of construction (con.- stituting no part of my invention, however) a clutch is provided, (designated generally at 20,) by which the drive-wheel 20, loosely' mounted upon its shaft, may be fixedly co'n-, nectedto its shaft in order to drive the pinion 21, thus providing means whereby to start and stop the operation of the machine.

Generally the machine comprises in its constructiou a number of dies; also, mechanism for bending and forming the fastener and for discharging it when completed from the machine. Mecha-nism for preparing the securing means, for cutting and bending the blank and for completing the fastener and expelling it from the machine is arranged on either side of the strip of continuous metal as it is fed into the machine. The feed mechanism is located at one side of the machine and is adapted to act upon the continuous strip to advance it with a stepvby-step movement at equal intervals through the machine and between the" dies and forming mechanism. The dies and bending and forming mechanism, as .Well' as the cut-off, are driven by cam-s mounted upon the shafts 24 and 25, andthese cams will be particularly described and pointed out as each member is described in connection with its operation upon the continuous strip.

I shall proceed to describe particularly at the outset the mechanism by which the continuous strip of metal (designated at J) is fed 7 through they machine with a step=by-step movement; Mounted upon the cam driveshaft 24 is a feed drive-cam 25, which operates to vertically reciprocate a connectingframe and feed drive-rod 26,-Figs. 2 and 3, to which the dependingspring-fingers 27 and 28 are secured- The spring-finger 27 carries a lug or head 29, which is adapted to engage,

one by one, the pins 30, projected from the face of the feed-wheel 31, near the periphery thereof. The spring-finger 28 also has a like lug or head 32 projecting from its lower end,

which is adapted to engage one arm of the pivoted bell-crank. dog 33, the end of the other arm of which is held, by means of the spring 34, normally in engagement within some one of the notches on the periphery of the feedwheel 3l. iy this means the feed-wheel 31 is positively withheld from any movement except when the lock of the bell-crank dog is withdrawn and the wheel released. This releasement is effected by the vertical reciproeative movement of the drive feed-rod 26, which causes the head 32 of the spring-finger 28 to engage one of the arms of the bell-crank dog 33 and withdrawits other end from looking engagement within one of the notches 35 upward thehead 20 has a preliminary movement before engagement with one of the pins 30. By this means the spring-finger 2S and its head 32 insure,- first, the withdrawal of the locking-dog to releasethe wheel 31,

and when this is accomplished then the head 29 of the spring-finger 27 engages one of the pins 30, and in the further upward movement of the drive feed-rod the feed-wheel 31 is rotated for a given predetermined distance until the pin 30 engaged has moved out of engagement w iththe head 29, and then the lockingpawl 33 again engages a notch in the periphery of the feed-wheel to hold it. securely against further feed. disengaged from the pin 30 the lug 32 has moved out of engagement'with the lockingdog "and the latter has closed against the periphery of the wheel 31, ready to drop into the first notch brought beneath-it. Therefore the release of the pin 30 and positive locking of the wheel occur simultaneously and the dog In the return cheeks against overdrive. movements of the-sliding frame the lug 32 rides over the locking-dog without affecting it. The feed-Wheel 31 is mounted upon a short counter-shaft 36, upon which the lower one of a pairfof gripping feed-wheels is mounted, (designated at 37,) the upper one being designated at 38. These gripping feed-wheels are adapted to bite and grip the strip J of metal between them and as they are rotated feed the strip intermittently through the machine by virtue of the movement imparted tothe lower grip feed-wheel 37 by the feed-wheel Before the head 29 is 31, The grip feed-wheel 37 is mounted within a housing 39, through which the strip-guide 40 is projected, this strip-guide serving to receivethe strip of metal and guide the same in its passage between the two feed grip-wheels 3S and 39. A presser shoe 41 bears upon '.the upper portion of the periphery of the grip feed-wheel 38, which is controlled by a spring 42. I v

' I will now proceed todescribe the means by which the dies form the eyelet and also the mechanism forforming the blank, cutting off theblank,bending and forming'the completed fastener, and expelling it from the machine. The eyelet die-blocks and 46 are mounted to reciprocate vertically toward and away from the common center upon either side of the continuous strip of metal J. The dieblock 46 carries the female members of the die, and the die-block 45 carrries the male members. The cam 47 on the cam-shaft 24 serves to drive the lower die-block 46, and the' cam 48 on the shaft 25 operates to drive the upper die-block 45. The cams, it will-be observed, bear directly against the head of an adjusting-screw 49. The earns 47 and 48 serve tomovethe die-blocks 45 and 46 vertically in one direction to perform the work upon the strip of metal J, and then the cams releasethe die-blocks and springs, to be designated, which act upon the die-blocks to move them in the opposite direction away from the strip of metal. These springs are more clearly shown in Fig. 4 and are designated at 52 and 53, held in back pieces of the frame, (designated at 54. These back pieces are recessed at 55 and 56, the springs 52 being disposed within the recesses 56 and bearing against stud-bolts 57, threaded to each ofthe die-blocks.

The punch 58 is carried .on the upper dieblock- 45 and is instrumental in fortningthe'.

eyelet of the completed fastener. This punch 58 serves to preliminarily form the eyelet of the fastener, and the punch 59 on said dieblock 45 completes the formation of the eye- 'let (59, as hereinafter explained.

It may be stated in passing that although the various members of the machine act simultaneously, as outlined, to form the eye-. let, out the blank, sever and bend the blank,

and complete the formation of the fastener it is necessary to describe the operation of the parts successivelyand then point out that the parts operate simultaneously to aecom-' ism is operated to advance the strip a sullieient distance to bring the indented portion of the eyelet (i'lesignated at (51, Figs. 8 and 17) into position beneath the punch 59 and that part which afterward becomes the crown 60" somewhatin advance of said punch.

construction by which the female member of- 46 is contracted to form a receiving-socket 64, slightly larger than the diameter of the larger portion of the eyelet-forming punch 59. A spring is disposed within the recess in the block 46 and is held fast at one end and bears at the. other end against the slidable block 62. The eyelet-forming punch 59 is shown more clearly in Fig. 8, and consists of the head 66 and perforating-pin 67,-projected from the head 66. The preliminarilyformed eyelet 61 is advanced by the'feed and rests within the socket 64 in the die-block 46, and its imperforate surface rests directly upfoxn thereof strikes the metal of the imperforate preliminarily formed eyelet 61 and forms therein a perforation, and the head 66 of'the punch 59 also at the same time draws the metal of the eyelet as theslidable block 62 descends under the pressure of the downwardly-moving die-block 45 and punch59. The small .portion of themetal cut out by the pin 67 falls through the channel 63 in the slidable block 62, and as the opening is continuous through the spring 65'this metal is discharged J nated at 69, 'Fig. 17) is completely formed. It is evident that the eyelet is .preliminag ril y formed by the punch 58 and its predeces- Thus theeyelet (desig-' sor com pletelyformedby the-punch 59 by one and the same movement of the dies 45 and 46 after the first formation.

blank out of the strip of metal. I prfovidea Iwill now proceed to describe the mechanism and means for cutting and forming the stationary die'formed in two parts and desfignated, respectively, at 70 and 71, located above the strip of. metal and adjacent to the movable die 45. The two-part die-block 7O 71 serves as an anvil to perform, in conjunction with the movable'die-block 72, the operation of cutting out-and forming the blank. The stationary die-block70, Fig. 10, carries the male portion of the die 73, and it is of an outline conforming to the shape of the completed but unsevered blank and of the crown (50 of the next succeeding blank. The movable die-block 72 has its upper surface formed to provide'the female member 74 of the die, as shown more clearly in Figs. 10 and 1 1. A movable die-bed 75 of'the outline of the com-- pletcd d ie is normally within the concavity or recess of the die-block'72, Fig. 11, its upper surface being flush with the surface of the said die-block. This die-bed 7 5 is mounted upon the slidable stem 76 within a recess in seated at its lower end and bearing at its upper end against the under end of the said slidable stem. A pin 78, fixed in the dieblock, Figs. 5 and 11, is projected into an opening 79, in the 'slidable stem '76, and thus serves tohold'the die-bed 75 in the properposition against the influence of the spring 77. The part '71 of the stationary die-block is bossed or convexed to formthe depression 80 of the blank, Fig.17, and this bossed or convexed portion is provided with the concavity or socket 81, Fig. 7. -The die-bed 75 on its,

, pleted eyelet as and when the strip is advanced in order that it "may rest flush and in line upon the dies.

It will be understood that the crown Q0 of the first blank is cut out upon one movement of the die-block 72 while the eyelet is being completed or is still resting in socket 6i and that then the metal strip, with the partiallyformed blank, is moved along by the feeding device, bringing the completed eyelet into position to enter recess 85 and an incomplete eyeletabove socket 64, and in the next movement of the die-block the neckSth-depression S0, and stud 83 of the blank are formed, toget-her with the crown of the succeeding blank, and the rim of the completed eyelet G9 is cut around, except a web, whereby it is left attached to said crown and held to the strip. When the die-block 72 is moved upward by its cam 72, the die-bed 75, having the female die, engages the under side of the strip of metal and is held in this position. As the die-block .72 has a movement-independent of the die-bed 7 5, it continues its upward movement, the die-bed remaining stationary. The female member of the die-bed and the male member of the stationary dieblock 71 hold the metal while the die-block 72 in its independent'movement cuts out the crown 60 of the first blank, the eyelet of which has just been or is being concurrently completed. The die-block 72 now recedes, and the strip of metal, with the cut-out crown and the completed eyelet, is fed forward until.the crown 60 is positioned between the members for forming the depression 9r cavity and striking up the locking-stud'83 and the completed eyelet is over the recess 85. The die-block is now moved upward -by its cam and the die-bed engages the cut-out crown 60, compressing and forming the concavity 8 0 ,-While the projection 82 and socket A spring 8 L bears against 81 together shape the locking-stud S3, of the completed fastener, and concurrently therewith the shearing edges of the die cut out the neck 86, the rim of the completed eyelet, and the crown 60;" of the next succeeding blank. The blank is now completely out out as to its longitudinal outline, butstill unsevered from the strip, and it remains to perform first the operation of bending the neck 86.

I will now. proceed to describe the mechanism and inannerof bending or looping the neck 86 of the blank and also cutting 05 a blank in advance of the one to be looped, the neck of which has already been bent or looped, it being understood that the feeding mechanism has advanced the cut-out blank into a position to be acted upon in order to form this loop or bent portion. The cam 87 on the cam-shaft 2-.t moves the loop-bending dieblock S8 vertically in the same manner as the other die-blocks are moved. The block 88 has a socket S9 for the reception of the completed eyelet, and thus permits the blank to lie hat and in line upon the face of the dieblock. As the die-block SS ascends, the upper die-block 90 is caused to descend by the cam 91 on the cam-shaft Thc die-block 88 carries a loop-former 9;, pivoted at 93 within a recess of the die-block 88, and this bending punch or head 92 is held normally against the side of the recess by means of the spring 94. The upper die-block 90 is recessed to receive a swinging carrier 95, pivoted at 96, the carrier 95 depending from said pivot 96 within the recess of the die-block. This carrier is also recessed to receive the movable die-plate 97, which has a slight movement independent of the carrier 95, and it is connected to a'slidable stem 98, against which bears the spring 39. A pin 100 engages within a slot 100, Fig. 9, of the movable die-plate 97, and thus is adapted to limit the movement of said die-plate independent of its carrier 95. The die-block 90 also carries the severing-knife 101. [he dieplate 97 has a concaved face to bend the loop in conjunction with the loop-former 92.

I will now describe the operation of the parts by which the loop is formed or bent in the neck 86 and the advanced blank,with the neck formed, out offor severed.- It is evident that the advanced blank, with its formed neck, must be cut off or severed from the continuous strip of metal before the loop can be formed in the ne'ck,'as the metal of the neck must be permitted to move laterally in order point the severing-knives 101-and 101, r-

spectively, Fig. 12, nponthe upper and lower die-blocks, withthe upper knife 101 slightly 7 stationary'position and the die-block'88 continnes to ascend, forcing the metal of the neck by the loop-former 02 into the'eoncavity of the die-plate 97, thus forming the bend or loop 102, as shown in Fig. 17. It will be onj derstood that in the formation of the loop the die-plate .97 recedes within its recess against the resisting influence of the spring 99 and when seated performs the operation of bending the 'loop.. As soon as the loop is bent and the die-block 90 rises the spring 99 moves the die-plate 97 downward, and thus expels the formed loop from the recess and from its contact with the die-.plate 97. Having now formed the loop 102 in'the neck of the blank,the strip of metal is advanced again by .the feed and it becomes necessary to bend the blank,with its formed loop, into the completed fastener. I will now proceed to describe the mechanism andmeans by which this result is accomplished. The block 103 is vertically moved die-block 113, operated by the cam 114 011 the cam-shaft 25. Ahammer-head 115 is pivoted into the completed fastener.

by the camlOi on the cam-shaft 24, and it is provided with a socket 105 for the reception of the completed eyelet as the blank on the strip, with the loop formed, is fed along into a position to bend or form the looped blank I This die-block 103 is recessed to receive the slidable stem 106, pivoted at 107, which stem is mounted upon the spring 108. Aspring 109 serves to press the stem 106 against the side of the re- The loop-holder 110 is carried on the slidable stem 1'06, and it is adapted to act in conjunction with the die-plate 1111,, having the transverse groove' 11-2, to hold the. loop and blank while the' upsetting and forming of the blank into a completed fastener takes place. This die-plate 111 is held within the at 116 within the die-block 103, and an actuating-rod 117 operates said hammer-head. This rod 117 is mounted withina recess in thedie-bloek 103 and is adapted to have a movement independent thereof. The cam 11S, mounted upon the cam-shaft 24, operates to vertically move the said rod 117. This cam 118 is provided with an offset 118, Fig. 4, which gives a sudden movement to the rod 117. The upperend of the said rod 117,which is'beveled or rounded, bears against the inclined face 110 on the hammer-head 115, and a spring 120, fixed at one end and secured at the other end to the halmner-head115, serves to retraet'the latter from an operating position. The operation of this portion of my device is as follows: The loop 102 is engaged first by the loop-holder 110 and the die-plate 111 as the die-blocks 103 and 113 are moved by their cams toward one another. \Vhen the loop is so engaged and held in position by the loop-holder 110 and the die-plate- 111,

the completed eyelet is within its socket andthe now-severed blank rests upon the shoulder 121 and the upper-face122 of the ham mer-head 115, as shownmore clearlyin Fig. 13. Just as soon as the die-plate 111 engages the top ofthe loop 102, in'conjunction with the loop-holder 110, the die-block 103 ceases to ascend, and, the upper die-block 113 continuing. to descend, the die-plate. 111 exerts a downward pressure upon the loop-holder 110 'against the resistance of its spring 108. The

loop-holder thendescends or sheaths within the recess of the die-block 103 into the positions shown 'in' Figs. 14 and 15; As the looped blank rests-upon the-shoulder 121 and upon the face 122" of the hammer-head 115 the downwardly-forced movement of the loop 102 upsets or bends the blank upwardly into the intermediate position, as shown in Fig;

14. In the continued descent of the die-plate 111 and the loop-holder 110 the loop is still sumes the position, as shown in Fig. 15, with the locking-stud 83 in a position opposite the transverse groove 112 of the die-plate 111.

At this point both the upper and the lower' dies are in .a stationary position. 'At this moment the cam 118 operates to thrust the rod'117 upwardly and advance the hammerthe upturned portion of the blank carrying thestud 83 and driving said stud into the 4 groove 112 of the die-'platell l, andby this means finishing and completing the formation of the fastener. The upper and lower dies then separate, andthe die-plate 111 of the upper die carries with it as. it recedes the completed fastener suspended to said dieplate by the engagement of the stud 83 of the fastener in the'groove 112 of the die-plate, as shown in Fig. 16, in readiness to be ejected from the machine. It remains now to release the completed fastener from its engagement with the groove 112 of the die-plate 111 and eject it from the machine.

In order .to expel or discharge the completed fastener, I provide the mechanism more clearly shown in Figs. 4 and 16. Pivoted to the front face of the upper die-block 113 is a lever 128, linked at" its lower end to the ejector head 1211. slides on the track 130, which latter is fixed on the die-plate 111 and extended outward therefrom. Secured to the frame 131 is an abutment 132, which projects forwardly from the frame into a position adapting it for engagement by the upper curved end 133 of the ejector-lever 128. This abutment 132 therefore maintains a stationary position at all times. A spring 13% serves to return the ejector-rod 129 and lever 128 into a normal position. The operation of this portion of my deviceis as follows: As previously stated,

the completed fastener is now held within This ejector head the transverse groove 112 of the die-block 111. As the ejector mechanism is carriedupon the face of the die-block 113 in the further ascent.

In so, doing the ejector-head 129 is also thrust inwardly toward the die-block, traveling upon its track 130, and strikes forcibly against the completed fastener suspended within the groove .of the die-plate.

. pact of the ejector-head against the-fastener pushes the finished and completed fastener out of the groove and discharges it from the machine into any suitable receptacle adapted to receive it.

It' should be clearly understood that these 1 steps,so called, successively described, are

each performed simultaneously-that is, these members for forming the eyelet, eutting the blank, severing and bending the blank, and completely forming the fastener act sim ultaneously and not successively one after the other. It is further evident that when the end of a'eontinuous strip is inserted into the machine under the specific arrangement chosen for the purposes of this description the first punch will form the'socket of the eyelet and that as the strip is fed along the eyelet will be completely formed, the crown cut, and the socket of another eyelet punched at the same time, and that with a still further feed the blank is trimmed and shaped and a punched socket'completedinto an eyelet and another socket formed. It is further evident that as the strip is fed forward again the loop of the blank is formed, another blank is trimmed and shaped, and another eyelet finished. and another socket for an eyelet formed. Bya still further feed the completed and looped blank is severed and completed into a fastener, and at the same time another blank is cut and looped, another eyelet completed, and another eyelet-socket punched. This action continues as the strip is fed forward into and through the'machine, each completed fastener being discharged in the manner described.

It Will be observed that the successive punches, cutting or shearing devices, stamps, bending mechanisms, blank-severing knives, and finishing-hammer are arranged in line, with the longitudinal axis of the shearinginstrumentalities coincident with the longitudinal axis of-the strip from which the blanks are cut, the planes of the bending and. blanksevering mechanisms transverse to said axis, and the fastener-finishing hammer swinging parallel with said axis; that, the feed-rolls and strip-guides are adapted to feed a strip of metal of width corresponding with the width of the widest part of the blank at any stage in the operation; that the successive blanks are formed heel to toe by shearing ed the lateral edges of the strip only where shear- This forcible iming is required, and that the ultimate sepa' ration of the blank from the strip is by a single cut on, the line separating its heel from the toe of its successor. Thus great economy of material is effected, the waste to be returned to the melting-pot or sent to lie scrapheap being reduced to a minim um.

I do not intend to be understood as limiting myself to the specific order of succession of the instrumentalities herein described, since it is evident that within restricted limits certain of them may be transposed without affecting the mode of operation of the machine or departing from the spirit of my invention; nor do I limit myself to the specific construction or outlines of such instrumentalities except as hereinafter defipitely expressed.

Havingthus described my invention, what I claim as new therein, and desire to secure by,
